Lightning Damage To An Alternator

AGI Lightning Damage To An Alternator

In an afternoon, three (3) alternators for the 3 generators were reported to have failed simultaneously, allegedly due to lightning activity. The reportedly damaged components included the main rotor coil, exciter rotor coil, Automatic Voltage Regulator (AVR), diodes, and bearings.

Vehicle Collision Investigation – Motorcycle and Motorcar

AGI Vehicle Collision Investigation

At about 1740 hours on Sunday, 29 September 2013, a motorcycle (hereinafter referred to as The Motorcycle) driven by Mr. X collided with a motorcar (hereinafter referred to as The Car) driven by Ms A was reported to have occurred at the traffic light junction of Jalan Semarak and the slip road onto the West-bound lanes of the ‘Duta-Ulu Klang Expressway’.

Failure of a Kiln Burner at a Cement Plant

AGI Failure Of A Kiln Burner At A Cement Plant

The operation for Kiln 3 at a cement plant was stopped at 11.25pm due to red spot (brick failure). Investigation indicates that the air channel pipe was “missing”, which resulted in a distorted flame shape. This is because the primary function of the air channel pipe is said to shape the flame and swirl the air whilst introducing the coal dust, to enable efficient combustion.

Water Damage Assessment

AGI Water Damage Assessment

Water, as simple as it sounds, can cause hundreds to thousands worth of damage. Various items can be damaged by water such as wood furniture, carpets, electronics and appliances in commercial buildings or residential households. Water damage can originate from different sources such as broken or leaking pipes, clogged pipes, water pump failure, natural disasters such as flood and rain. Insurance policy normally would cover the cost associated with water damage. Hence, water damage assessment is important to verify the water-affected items as well as to determine the severity of the damage.

Crane Failure Investigation

AGI Crane Failure Investigation

At approximately 0840 hours on Thursday, 1 August 2013, it was reported that hoist crane No ‘2’ had fallen after hoisting a set of screws. Further inspection conducted on the hoist crane revealed that one of the planetary wheel gears inside the gearbox had fractured. No casualty was reported at that time as the mill was not in production.

AGI Infrared Thermography

Approved’s comprehensive reports pinpoints the exact cause of problems that threaten the integrity of a company’s electrical and mechanical systems and the identification of damage to water systems. Our thermographers are trained, certified and experienced in thermal infrared scanning.

Collision Damage Classification

AGI Collision Damage Classification

Collision Damage Classification (CDC, per SAE MAR80 J224) is an excellent tool to provide a clear and concise description to the principal direction of force (PDoF) onto a motor vehicle during a vehicular accident investigation and reconstruction.

The standard was developed by the federal United States government to simplify the description of damage, where the direction of PDoF at point of impact (POI), vehicle deformation location, general type of collision, and damage scale are entailed and coded by numbers and letters.

Fire Debris Collection for Instrumental Analysis

AGI Debris Collection Image 1

Persistence of ignitable liquid residues at fire scenes can challenge the most experienced fire investigator. The recovery of Ignitable liquid residue requires knowledge, experience, skill and a certain amount of luck. John has recently presented a paper titled “Fire Debris Collection for Instrumental Analysis” at “The Evidence Conference”, delivered in Washington DC and this article aims to provide a summary of his paper.
